Characteristics of OWC Type WEC Dampers Installed on a Very Large Floating Structure

Tomoki Ikoma, Shoichiro Furuya, Yasuhiro Aida, Koichi Masuda, Hiroaki Eto
Proc. ASME. OMAE2020, Volume 5: Ocean Space Utilization, V005T05A027, August 3–7, 2020
Paper No: OMAE2020-19002
DOI: https://doi.org/10.1115/OMAE2020-19002
... Abstract Oscillating water column (OWC) type wave energy converters (WECs) have been researched and developed. OWC WECs are relatively friendly to maintain them in operation because all of mechanical units are set above a sea water surface. In addition, a feature of an OWC device is similar...

Experimental and Numerical Investigations on Wave Dynamics of a Dual-Chamber OWC Wave Energy Device

Dezhi Ning, Rongquan Wang, Bin Teng, Qingping Zou
Proc. ASME. OMAE2019, Volume 9: Rodney Eatock Taylor Honoring Symposium on Marine and Offshore Hydrodynamics; Takeshi Kinoshita Honoring Symposium on Offshore Technology, V009T12A001, June 9–14, 2019
Paper No: OMAE2019-95165
DOI: https://doi.org/10.1115/OMAE2019-95165
... Abstract Oscillating Water Column (OWC) wave energy device is one of the most studied and applied wave energy converters (WECs). The survivability of WECs is a major concern in the OWC design. In this study, the wave dynamics of a dual-chamber OWC device is numerically and experimentally...

The Effect of Plenum Chamber Volume and Air Turbine Hysteresis on the Optimal Performance of Oscillating Water Columns

Matt Folley, Trevor Whittaker
Proc. ASME. OMAE2005, 24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 2, 493-498, June 12–17, 2005
Paper No: OMAE2005-67070
DOI: https://doi.org/10.1115/OMAE2005-67070
... 19 11 2008 It is well known that air compressibility is likely to influence the performance of oscillating water columns (OWC’s) and this has previously been modelled and estimated using linear aero-hydrodynamic lump-mass models. In addition, the optimum performance of specific OWC’s...
